Patent CA-2320700-A1 (CA)
Title: A method and apparatus for cryptographically secure algebraic key establishment protocols
Inventor: ANSHEL IRIS
IPC: H04L9/08
Filed: 1999-02-25
Abstract: The present invention is a method and apparatus for providing cryptographically secure algebraic key establishment protocols that use monoids and groups possessing certain algorithmic properties. Special fast algorithms associated with certain monoids and groups are used to optimize both key (63) agreement and key transport protocols (62). The cryptographic security of the algorithms (23) is based on the difficulty of solving the conjugacy problem in groups and other known hard algebraic problems. Braid groups and their associated algorithms are the basis for highly rapid key agreement and key transport protocols which employ modest computational resources.

Title: Compositions and methods for the treatment of cystic fibrosis
Inventor: PERRINE SUSAN P
IPC: A61K31/195
Filed: 1999-02-11
Abstract: The invention is directed to novel pharmaceutical compositions comprising chemical agents that are useful in the treatment and prevention of cystic fibrosis and the prevention of signs and symptoms of this disease. These pharmaceutical compositions are surprisingly successful in the treatment of disorders related to cystic fibrosis including disorders of blood production. Many of these compositions of the invention are even more effective when administered to a patient in pulses. Pulse therapy is not a form of discontinuous administration of the same amount of a composition over time, but comprises administration of the same dose of the composition at a reduced frequency or administration of reduced doses.
Patent CA-2325431-A1 (CA)
Inventor: LOU HUI-LING
IPC: H03M13/00
Filed: 2000-11-07
Abstract: Unequal channel error protection is provided for a bit stream, e.g., a progressive source coded bit stream, by puncturing of a channel code. The channel code has a specified rate associated with a corresponding level of error protection, and is used to code a first portion of the bit stream. The channel code is subsequently punctured for at least a second portion of the bit stream so as to provide a rate higher than that of the designated rate. Commencement of the puncturing is deliberately delayed by an amount determined based at least in part on a memory of the channel code. Advantageously, the delay prevents propagation of errors in a channel decoder used to decode the channel coded bit stream. The progressive bit stream may be a progressive source coded video or audio bit stream, any other type of progressive information bit stream, or a partitioned source coded bit stream.

Patent CA-2344633-A1 (CA)
Inventor: BABISH JOHN G
IPC: G01N33/50
Filed: 1999-09-17
Abstract: According to the present invention, the biological or pharmacological activity of a test material like a plant or herbal material, an extract of a plant or herbal material, a natural or synthetic compound or some combination thereof, can be quantified by observing the pattern of structural changes induced in a eukaryotic cell's proteins. These structural changes may be evidenced by protein phosphorylation, by protein-protein interactions and the like. The amount and nature of protein phosphorylation is qualitatively and quantitatively related to the in vitro concentration of biologically/pharmacologically active components to which the mammalian cells are exposed. Additionally, formation or loss of protein-protein complexes may be determined in whole cell homogenates through the use of nondenaturing electrophoresis and staining for proteins or protein phosphorylation. The present invention allows natural products to be formulated into nutritional supplements and pharmacological preparations of consistent biological/pharmacological activity without the need to identify any of the chemical constituents responsible for the biological or pharmacological response.
